Geological Record of Oman

Super-sequence 'A' in Oman consists of rocks forming the continental crust and the sediments above it which were present before the opening of the Tethys Ocean. It includes pre-Permian rocks (older than 600 million years) and shallow water carbonates deposited on the Arabian platform as a result of the opening of the Tethys Ocean.

Super-sequence 'B' in Oman consists of rocks formed away from the continental edge, including those from the slope and into the deep oceanic floor as well as the Tethyan oceanic crust (Ophiolite).

Super-sequence 'C' in Oman consists of rocks formed after the closure of the Tethys Ocean and the arrival of the ophiolite. These rocks are shallow marine limestones and referred to as Tertiary rocks. The formation timeline is from 65 to 2 million years ago.

Super-sequence 'A' in Oman includes pre-Permian rocks and shallow water carbonates, formed before the opening of the Tethys Ocean. In contrast, Super-sequence 'B' consists of rocks formed away from the continental edge, including those from the slope and into the deep oceanic floor as well as the Tethyan oceanic crust (Ophiolite).

The tectono-stratigraphy of Oman includes three main super-sequences: 'A', 'B', and 'C'. Super-sequence 'A' consists of Super-sequence APP (pre-Permian) and Super-sequence AC (Hajar Super-group). Super-sequence 'B' includes Ophiolite BO and Hawasina BH. Super-sequence 'C' is comprised of Tertiary CT rocks.
